(sorry for the length of this message)
I was thinking today about how the phone system is quite dead without no one
noticing it. We are paying unreasonable tariffs for just sending data which
happens to be voice. The whole motivation behind having a number is no longer
existent as with portability and roaming you don't do switching anymore.
So you don't want to access the telephone network, you want to access the
Internet, then do whatever you want from there.
Yes in the meantime you may still want to do normal calls but the focus is in
doing VoIP and IM.
Because of this I think the next moko should be designed around this and be
mainly a handheld. With no included GSM module so you can focus in the
interesting part of the product and don't bet on the next mainstream
communication technology (mobile wimax? UMTS? EDGE? CDMA something?) and just
provide the one you are sure they will be supported for much time (wifi,
bluetooth).
Then you just provide some module to access the chosen network, like a SDIO
card (probably with a big external part like most wifi ones).
I was thinking of a beast like a bluetooth UMTS dongle. There are already USB
UMTS dongle right now which emulates a serial port. So it's a no brainer to
take an existing design, strip the usb-serial chip and put a bluetooth-serial
chip and a battery (the usual nokia one which most GPS and the Neo uses).
This gives the advantage of not having a powerful antenna attached to the ear
(when talking) or anyway near you (when messaging, browsing).
You can put it near a window and get better signal, and so on.
Of course some may find the SDIO more appealing or not. Anyway if you keep
this component separated you let the user choose whether they really need
GSM, you can develop the hardware WAY faster and most important, you don't
have to wait for the comm. modules to be functional to start selling, and if
a comm. module happens to be a total market/design/whatever failure you still
have the main product (the handheld) selling well.
Just my (long) 2 ¢
